Hi! Can you help me?
I try to use Anko + SQLite
Create table:
db.createTable("my_table", true,
"_id" to INTEGER + PRIMARY_KEY + UNIQUE,
"lat" to REAL,
"long" to REAL,
"radius" to INTEGER
)

I have the class
class Location(val _id: Int, val lat: Double, val long: Double, val radius: Int)

When i try
val rowParser = classParser<Location>()
return instance!!.writableDatabase.select("my_table", "_id", "lat", "long", "radius").parseList(rowParser)
i have exception Can't initialize object parser for ....Location no acceptable constructors found
